Abstract: P/8621/Special ABSTRACT   (Figure 1,2) Analogue-to-Digital converters. Digital-to-Analogue Converters  and Digital Modulators In  order  to improve the signal-to-noise ratio  of  a known sigma-delta analogue-to-digital converter A, the input to the  loop filter means 3, 4 (which can be regarded as  an error signal  between  the  analogue   input  and,  ignoring imperfections  in  the digital-to-analogue converter 8,  the analogue  equivalent  of the digital output),  is  filtered, amplified  and  converted  to a digital signal in  a  second sigma-delta  converter  B.  This digital signal is  combined with the digital output of the analogue-to-digital converter A to produce  an  output  of the two  stage  converter  with improved  signal-to-noise ratio.  Phase and amplitude errors introduced  before the signals are recombined are  corrected for by  an  equalisation  network  which  is  calibrated  at regular intervals by means of a test generator 18.  The same technique  can be employed to produce a  digital-to-analogue converter,   and   a  digital   modulator,   with   improved signal-to-noise ratio.

Abstract: On a modifié le facteur VII de la cascade de coagulation afin qu'il agisse en tant qu'anticoagulant. On a utilisé des modifications d'acides aminés afin de produire un facteur VII modifié présentant une faible susceptibilité d'activation par des enzymes activant habituellement le facteur VII de type sauvage. Le facteur VII modifié est capable de concurrencer le facteur VII et/ou VIIa de type sauvage dans la liaison du facteur tissulaire, inhibant l'activité coagulante. Comme le facteur VII modifié agit spécifiquement pour interrompre la cascade de coagulation, on peut administrer des compositions pharmaceutiques de facteur VII modifié à la place de thérapies anticoagulantes classiques, ou conjointement avec de plus faibles doses de ces dernières.

Filed: 1991-04-26
Abstract: The present invention provides a mobile communications system in which the home exchange of a mobile subscriber maintains information indicative of where the mobile subscriber might be found. Upon receipt of a call, the home exchange requests the exchange where the mobile is believed to be located to page it and then requests the answering exchange(s) to order the mobile to tune to a voice/traffic channel.      Only after the successful completion of this process does the answering exchange report this to the home exchange which then orders routing of the call through the network.

Title: Water arrow projecting bow
Inventor: JOHNSON LONNIE G
IPC: B05B9/04
Filed: 1993-03-26
Abstract: ABSTRACT OF THE DISCLOSURE          The present invention is a toy water bow which is operated by selectively releasing water from a water reservoir that is pressurized with air.          The present invention is a toy device formed in the general shape of an archery bow that has a manually operated air pump incorporated into it.          The air pump pressurizes a water reservoir and consequently exerts pressure on water contained therein.  The pressurized air and water have an avenue of release that is regulated by a pull mechanism of the invention.  When no force is applied to the pull mechanism, the pressurized air and water are held at bay with no means of release from the reservoir.  When force is applied to the  pull mechanism in a predetermined manner, water is released from the pressurized reservoir and is channeled through a narrow nozzle.  The escape of the water through the narrow nozzle creates a stream of propelled water in the form of an "arrow" of predetermined length   The shooting may be repeated until the water is consumed or until the pressure of the reservoir equals that of the ambient air.

IPC: E21B44/00
Filed: 1993-05-05
Abstract: A method of detecting a drillstring washout during an operation involving the addition or removal of pipes from the drillstring such as back reaming, comprising: a) performing at least one such operation and determining by hydraulic coefficient k from the relationship P = kQ a, where Q is the flow rate, P is the standpipe pressure and a is the flow exponent, from each pipe added or removed, so as to derive a series of values indicating the development of k for said operations, and b) on subsequent operations, determining k and comparing the determined values with the series obtained previously, a drillstring washout being detected when the determined value of k falls substantially below the corresponding value of k in the series. The trend in the development of k can be calculated and used to determine if an anomaly exists in the determined value of k.

IPC: D06P3/24
Filed: 1991-11-08
Abstract: A process for the dyeing of a fibrous article containing fibers of a polyamide polymer with an anionic dye and dyed pro-duets made by the process. The process includes immersing the article in a dyeing bath of a liquid solvent for the anionic dye. The liquid solvent and the article are heated to a temperature at least equal to the dyeing transition temperature of the fiber of polya-mide polymer. The anionic dye is added to the dyeing bath as a miscible liquid concentrate at a dye addition rate during a con-trolled dye addition period. At least a portion of the dye is added while the solvent and the article are at a temperature at least equal to the dyeing transition temperature. Stirring of the bath during the dye addition period and while the solvent and article are at a temperature at least equal to the dyeing transition temperature is done to mix the dye concentrate with the solvent in the bath to form a dilute dye solution and to provide a flow of the dilute dye solution relative to the article to cause the dye to be transported to the article. The stirring also provides, on the average, essentially uniform dye transport of the anionic dye to the article. The dye addition rate is adjusted at least while the solvent and article are at a temperature at least equal to the dyeing transition temperature so that the dye addition rate is the primary control over the rate of dye uptake by the article.
